.1. sYLvAN WINDOW SCREEN Filed June 18, 1945 IN VEN TOR. JOSEP/l 5m Vfl/V MW Y@ ArroP/vfy i Patented pr. 26, 1949 UNITED STATES PATENT OFFICE WINDOW SCREEN Joseph Sylvan, Berkley, Mich. Application June 18, 1945, Serial No. 600,019

(Cl. i60- 375) 7 Claims.

This invention relates to improvements in window screens.

An object is to provide a window screen having a metal frame which frame is particularly adapted to be easily and quickly adjusted to fit window openings of slightly different size.

Another object is to provide a window screen having a metal frame provided with one or more window jamb engaging Istrips which strips are adapted to be adjusted relative to the frame to make the screen frame fit the Window opening. More particularly the metal frame exhibits outwardly open folds or channels extending along certain margins and the adjustable marginal jamb engaging strip is frictionally adjustably received within such outwardly open fold or channel formed in the metal frame. The strip is resistingly adjustable inwardly or outwardly within the channel to increase or diminish a dimension of the screen frame.

A meritorious feature is that this adjustable marginal strip is not only adjustable within the channel relative to the screen frame member but the strip includes an outer marginal flange which is bendable to vary the overall dimension of the screen frame.

Another object is to provide a screen having a metal frame wherein the frame parts, the end frame members and the top and bottom frame members, are so constructed and interlocked toq.

gether at the ends and without the use of auxiliary fastening means as to provide a simple, rigid, light weight and inexpensive screen structure.

Other objects, advantages and meritorious features will more fully appear from the following description, appended claims and accompanying drawing, wherein:

Figure 1 is a front elevation of a screen structure embodying this invention.

Figure 2 is -a horizontal sectional View taken on the line 2 2 of Figure 1.

Figure 3 is a vertical sectional the line 3-3 of Figure 1.

Figure 4 is a perspective of a corner fragment of a screen frame showing an adjustable jamb strip in position.

Figure 5 is a perspective of a corner fragment of a screen frame showing the adjustment strip separated therefrom.

Figure 6 is a rear elevation of a ycorner fragment of this screen.

This screen structure represents an improvement upon or modification of the screen structure illustrated in my pending patent application Serial No. 592,339, filed May 7, 1945.

The screen mesh wire is indicated as I0. It is cut over size the opening defined by the screen frame and is folded along each margin, as at I2, over an angular fiange I4 of the screen frame. It

view taken on is stretched taut across the frame opening and securely held upon said flange I4 by a channel retaining strip I as described in the patent application above referred to.

The screen frame illustrated comprises a top frame member 20, a bottom frame member 22 and two end frame members 24. Each of these frame members is provided with its flange I4 and a channel retaining strip I6 is provided for the flange of each frame member. These flanges collectively form a substantially continuous flange about the frame opening. These channel retaining strips are pinched tightly upon the screen wire I0 holding the wire against the flanges I4 over which they are received as shown in Figures 1 and 3. These channel retaining strips are interlocked together at the corners as shown in Figures 1 and 5 by having end laps or extensions I8 folded over each other as shown in the draw- The top and bottom frame members 20 and 22 respectively are folded over inwardly as at 26 as shown particularly in Figure 3. The inner margin of the top frame member 20 is bent upwardly at an acute angle to the plane of the frame member to form the upper flange i4 heretofore referred to. The inner margin of the bottom frame member 22 is bent downwardly upon itself at an acute angle to the plane of the frame member to form -corresponding bottom flange I4 heretofore referred to. The ply 26 of the top frame member projects at each end as at 29 beyond the ply 20 of such member and the ply 2B of the bottom frame member projects at each end as at 29 beyond the ply 22 of such member.

Each end frame member 24 is folded over along its inner margin outwardly upon itself as at 30 forming an outwardly open channel. This out- Wardly extending fold 30 is also bent along its outer margin as shown in Figure 2 to form the end retaining flange 'I4 for the screen wire. The outer margin of each end frame member 24 is folded over inwardly upon the frame member as at 32. This fold 32 laps over the projecting ends 29 of the top and bottom frame members 20 and 22 respectively as shown in Figures 2, 4, 5 and 6 thereby securing the end frame members 24 and the top and bottom frame members 20 and 22 together to form a complete rugged screen frame structure.

The outwardly open channel in each end frame member 24 formed by the fold 30 is adapted to snugly frictionally adjustably receive an angular jamb engaging adjustment strip 34 as shown. Each adjustment strip 34 is provided with an angular channel fold 36. The outer wall 31 of this channel fold 36 is adapted to fit snugly against against an end jamb within the window opening. The strip 34 may be withdrawn outwardly relative to the end member 24 or projected inwardly relative thereto to accommodate the screen'frame to window openings of different size.

To further facilitate the engagement ci the ends of the screen with'the side jambs of the window opening and to accommodate the screen frame to window openings of diierent size the channel ange 36 may be spread apart or closed together. If desired the channel flange 3? may be bent as a unit relative to the plane .of the member 3'4 in which event the outer wall 31 of the channel 36 will lie at against 'the side jamb of the window opening at dierent positions of adjustment. On the other hand the side wall 3'7 may be bent outwardly angularly to increase the overall vdimension of the screen.

The adjustment strip .34 may be disposed within the .open channel of the end frame member 24 in such a manner that the iange 3'6 may project either toward the front face `or .toward the rear face of thescreen unit whichever may be ldesired tending along its outer margin and projecting angularly with respect to the plane of the strip.

5. A screen sash having a frame member formed of sheet metal and folded upon itself forming a channel opening outwardly along the outer margin of the frame, a jamb engaging strip frictionally adjustably receivable within said channel and extending lengthwise thereof, said for purposes o'f engagement with or -securement to the window screen opening in .a wall.
